Experts have finally been able to confirm the existence of cosmic particle accelerators in our galaxy, the Milky Way, after years of studies. Astrophysicists have known for a long time that some galaxies have portions that are capable of acting like giant particle accelerators, forcing various particles to move at ne... |

Muscles remember their former fitness even when they atrophy from lack of use, as this memory is stored as DNA-containing nuclei, that develop when a muscle is exercised, a new research published online August 16 in the Proceedings of the National Academy of Sciences reports.This research sustains the fact that exerc... |

Astronomers have for a long time attempted to develop methods of predicting when a comet will begin to emit dust and ice particles from its central region. Called a nucleus, these areas look like they are made of rocks, but they are in fact made of frozen ice. In a recent investigation, a team of experts was finally ... |

An international collaboration of researchers has recently managed to make substantial headway in their study of the human genome. The investigators were able to gain new, thorough insight into the functional organization and arrangement of the human genetic material, and the data they collected is presented in a pap... |

Physicists in Japan have recently discovered an exotic form of carbon, one that features an extra-large halo nucleus. The central region of this atom is so large, that it even puts to shame the nuclei of heavier chemical elements such as copper and zinc. However, the new material does not exist in nature, as it was p... |

As more and more work was conducted on the human cell and its components, researchers noticed some time ago that chromosomes tended to appear in various parts of the cells during specific stages of cell division. This naturally led researchers to believe that the structures were moving about, but no one was able to d... |

Whilst conducting a new series of experiments involving the analysis of protons, scientists at the US Department of Energy's (DOE) Thomas Jefferson National Accelerator Facility (Jefferson Lab) discovered that the companions protons had inside the atomic nuclei changed the positive particles' internal stru... |

Established astronomical knowledge had it that galaxies with two nuclei were very rare. Experts believed that small galaxies had one made up of a star cluster, whereas the more massive ones had a black hole at their cores. But a new study comes to prove that the double-nucleus galaxy is, in fact, not that rare of an ... |

In a new research paper, appearing in the latest issue of the journal Meteoritic & Planetary Science, a team of experts from the Monash University, led by Dr. Maria Lugaro, proposes a new explanation for why the chemical composition of the early solar system looks the way it does in geological records. The scientists... |

Protons and neutrons are the basic constituents of the atomic nucleus. Understanding the interactions between the nucleons may provide some insight towards understanding the structure of the nucleus in light nuclei and neutron stars alike. An experiment carried out at the US Department of Energy's Thomas Jeffers... |

Nickel 56 is one of nickel's unstable isotopes which is not occurring naturally here on Earth. However, it is formed during the supernova explosion at the end of a star's life. Physicists from the IPN Orsay and the GANIL claim they have been able to compress the nucleus of Nickel 56 for the first time, in o... |

Isomers are very important to scientists mostly because their ground state atomic nuclei can provide with valuable information regarding interactions between the protons and neutrons present inside the nucleus. Some isomers may only live for a few fractions of a second while others, for millions of years at a time, t... |

Stars spend most of their lives burning hydrogen through nuclear fusion reactions to produce the energy required to remain stable as long as possible. By doing so, two hydrogen atoms are fused together to create a single helium atom and a fair amount of energy. However, at some point in time, the star will begin proc... |

While in school, science taught us that atoms are made of two major components: the nucleus and the electronic shell orbiting around nucleus. Atoms may lose or gain electrons and neutrons during certain interactions. The number of neutrons inside an atom determines the type of isotope associated with the respective c... |

When cruising in your car, a police laser radar can easily measure your speed and send the ticket to your door, probably along with a picture showing your big grin at 160 km/h (100 mph). But when it comes to observing particles traveling at 1/3 the speed of light - 100,000 km/s - things get a bit complicated.Even the... |
